I am trying to use the OpenCV's cascade classifier based on Histogram of Oriented Objects (HOGs) feature type -- such as the paper "Fast Human Detection Using a Cascade of Histograms of Oriented Gradients". Searching in the web, I found that the Cascade Classificator of OpenCV only supports HAAR/LBP feature type (<a href="http://opencv.willowgarage.com/documentation/cpp/objdetect_cascade_classification.html" rel="nofollow">OpenCV Cascade Classification</a>). <ul> <li>Is there a way to use HOGs with the OpenCV cascade classifier? What do you suggest? </li> <li>Is there a patch or another library that I can use?</li> </ul> Thanks in advance! EDIT 1 I've kept my search, when I finally found in <a href="https://groups.google.com/forum/?fromgroups#!topic/android-opencv/Smu-0aEzsPw" rel="nofollow">android-opencv</a> that there is a trunk in Cascade Classifier which allows it to work with HOG features. But I don't know if it works... Link: <a href="http://code.opencv.org/projects/opencv/repository/revisions/6853" rel="nofollow">http://code.opencv.org/projects/opencv/repository/revisions/6853</a> EDIT 2 I have not tested the fork above because my problem has changed. But I found an interesting link which may be very useful in the future (when I come back to this problem). This page contains the source code of the paper "Histograms of Oriented Gradients for Human Detection". Also, more information. <a href="http://pascal.inrialpes.fr/soft/olt/" rel="nofollow">http://pascal.inrialpes.fr/soft/olt/</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
